The disclosure generally relates to feet for outdoor furniture and, more particularly, to feet for an outdoor chair.
This section provides background information related to the present disclosure which is not necessarily prior art.
It is sometimes useful or necessary to attach one or more floor contacting parts to injected molded plastic furniture, such as a foot. One benefit of using the foot is to provide the article of furniture with improved friction in order to reduce slippage of the article on smooth surfaces. Another is that, when feet are used on an article of furniture with legs such as a chair or table, the amount of internal stress the article must withstand when a load is applied is reduced. The internal stress reduction achieved by using feet can be very significant. Chairs with feet can hold a set weight before failing much longer than a chair provided without feet, where failure can be the result of the legs slipping and splaying under the weight. For instance, in one example, a chair provided with feet resistant to slipping can hold a set weight for over an hour without splaying, but can hold the same weight for only about 1 minute without feet before splaying and compromising the structure and function of the chair. For that chair, and for many other articles of furniture, feet are critical and integral structural and functional components. Other reasons feet may be used are to cushion impacts on the furniture or to protect substrates from being scuffed by the more rigid material comprising the furniture.
Feet are conventionally provided as plastic or rubber caps coupled to terminal ends of the legs of the chair. These caps can rely on a friction fit design that may not perform adequately in certain situations and can fail to remain attached to the legs. Other examples of conventional feet include those coupled to the chair via a bolt and nut fastener. Although these fasteners may remain coupled to the legs of the chair, the weight, complexity, and assembly of the chair is undesirably increased with the addition of such fasteners. Further, such chairs can be more difficult to stack, which is becoming increasingly popular with storing outdoor furniture. Lastly, certain fasteners, including metal fasteners, are not an economical choice for manufacturers in producing low cost outdoor furniture.
Accordingly, there is a need for an improved foot for an article of outdoor furniture that has enhanced durability, provides a means to adequately retain the foot to the article of outdoor furniture, and does not greatly add to the cost of manufacturing the furniture.
In concordance with the instant disclosure, an improved foot for an article of outdoor furniture that has enhanced durability, provides a means to adequately retain the foot to the article of outdoor furniture, and does not greatly add to the cost of manufacturing the article of outdoor furniture, has been surprisingly discovered.
A foot for an article of outdoor furniture is provided that includes an anchor portion and a base pad. The anchor portion may include a prong system that is configured to provide a friction fit retention means when the foot is coupled to an article of outdoor furniture. A top surface of the base pad may be coupled to the a bottom surface of the anchor portion. The prong system may extend from a top surface of the anchor portion.
A foot for an article of outdoor furniture may be used as part of an outdoor furniture foot system. The outdoor furniture foot system may include a foot for an article of furniture that includes an anchor portion and a base pad. The anchor portion may include a prong system that is configured to provide a friction fit when the foot is coupled to the article of outdoor furniture. The base pad may be coupled to a bottom surface of the anchor portion. The outdoor furniture foot system may further include an article of outdoor furniture configured to be coupled with the foot for an article of outdoor furniture.
The foot may be coupled to an article of outdoor furniture by various methods. One method may include a step of providing a foot having a base pad and an anchor portion. The anchor portion may include a prong system that includes a friction fit retention means which is configured to couple the foot to an article of outdoor furniture. A top surface of the base pad may be coupled to a bottom surface of the anchor portion. An article of outdoor furniture having a substantially vertical wall configured to be accepted by the prong system may be provided. The method may include inserting the prong system of the foot into the article of outdoor furniture, wherein the substantially vertical wall is wedged within the prong system, thereby coupling the foot to the article of outdoor furniture.
Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
The following description of technology is merely exemplary in nature of the subject matter, manufacture and use of one or more inventions, and is not intended to limit the scope, application, or uses of any specific invention claimed in this application or in such other applications as may be filed claiming priority to this application, or patents issuing therefrom. Regarding methods disclosed, the order of the steps presented is exemplary in nature, and thus, the order of the steps can be different in various embodiments, including where certain steps can be simultaneously performed. “A” and “an” as used herein indicate “at least one” of the item is present; a plurality of such items may be present, when possible. Except where otherwise expressly indicated, all numerical quantities in this description are to be understood as modified by the word “about” and all geometric and spatial descriptors are to be understood as modified by the word “substantially” in describing the broadest scope of the technology. “About” when applied to numerical values indicates that the calculation or the measurement allows some slight imprecision in the value (with some approach to exactness in the value; approximately or reasonably close to the value; nearly). If, for some reason, the imprecision provided by “about” and/or “substantially” is not otherwise understood in the art with this ordinary meaning, then “about” and/or “substantially” as used herein indicates at least variations that may arise from ordinary methods of measuring or using such parameters.
Although the open-ended term “comprising,” as a synonym of non-restrictive terms such as including, containing, or having, is used herein to describe and claim embodiments of the present technology, embodiments may alternatively be described using more limiting terms such as “consisting of” or “consisting essentially of.” Thus, for any given embodiment reciting materials, components, or process steps, the present technology also specifically includes embodiments consisting of, or consisting essentially of, such materials, components, or process steps excluding additional materials, components or processes (for consisting of) and excluding additional materials, components or processes affecting the significant properties of the embodiment (for consisting essentially of), even though such additional materials, components or processes are not explicitly recited in this application. For example, recitation of a composition or process reciting elements A, B and C specifically envisions embodiments consisting of, and consisting essentially of, A, B and C, excluding an element D that may be recited in the art, even though element D is not explicitly described as being excluded herein.
As referred to herein, disclosures of ranges are, unless specified otherwise, inclusive of endpoints and include all distinct values and further divided ranges within the entire range. Thus, for example, a range of “from A to B” or “from about A to about B” is inclusive of A and of B. Disclosure of values and ranges of values for specific parameters (such as amounts, weight percentages, etc.) are not exclusive of other values and ranges of values useful herein. It is envisioned that two or more specific exemplified values for a given parameter may define endpoints for a range of values that may be claimed for the parameter. For example, if Parameter X is exemplified herein to have value A and also exemplified to have value Z, it is envisioned that Parameter X may have a range of values from about A to about Z. Similarly, it is envisioned that disclosure of two or more ranges of values for a parameter (whether such ranges are nested, overlapping, or distinct) subsume all possible combination of ranges for the value that might be claimed using endpoints of the disclosed ranges. For example, if Parameter X is exemplified herein to have values in the range of 1-10, or 2-9, or 3-8, it is also envisioned that Parameter X may have other ranges of values including 1-9, 1-8, 1-3, 1-2, 2-10, 2-8, 2-3, 3-10, 3-9, and so on.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer, or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the FIGS. is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
As shown in
In certain circumstances, as illustrated in
The base pad 104 may absorb and distribute force applied to the anchor portion 106. In particular examples, the base pad 104 may compress or deform, equalizing the force experienced by different sections of the anchor portion 106. In this way, the base pad 104 may alleviate the forces exerted on the anchor portion 106 and provide additional stability to the foot 100 as well as the article of outdoor furniture 102. This distribution of force may be particularly useful for ground surfaces which create uneven points of contact, or when the article of outdoor furniture 102 is moved or jostled. Additionally, when multiple feet 100 are affixed to an article of outdoor furniture 102, each of the feet 100 may experience a disproportionate amount of force. The base pad 104 of the foot may selectively flex and distribute the force appropriately to the anchor portions 106, thereby mitigating stress placed on the article of outdoor furniture 102.
As illustrated in
In certain examples, co-extrusion may also allow the different materials to maintain desired characteristic properties while allowing the materials to merge or weld together into a single structure before cooling. One skilled in the art may select other suitable configurations for coupling the anchor portion 106 to the base pad 104, within the scope of the present disclosure.
As shown in
As a non-limiting example, the inner surface 127 of the uppermost tooth 128 of the array of teeth 112 may form a plane A which defines an angle X therebetween a plane B defined by the tops 109, 111 of the prong system. The angle X may be configured to guide the substantially vertical wall 124 into and between the pair of prongs 108, 110. In certain examples, the angle X of the uppermost tooth 128 may vary between a range of zero degrees to one hundred eighty degrees. In a particular example, the angle X of the uppermost tooth 128 and a similar angle defined by each top of the array of teeth 112 and plane B may differ. In a more particular example, the angle X of the uppermost tooth 128 may be around forty-five degrees.
As shown in
In particular examples, the anchor portion 106 may be constructed from a first material and the substantially vertical wall 124 may be constructed from a second material. In a more particular example, the first material may be a harder material than the second material. In a most particular example, the hardness of each material may be determined by a durometer hardness on the ASTM D2240 standard Shore durometer scales. Advantageously, the array of teeth 112 of the anchor portion 106 may more easily bite into the substantially vertical wall 124 where the material constructing the anchor portion 106 is harder than the material forming the substantially vertical wall 124. This can be particularly advantageous when the substantially vertical wall 124 has not fully hardened, further assisting the array of teeth 112 in biting into the substantially vertical wall 124.
As depicted in
The article of outdoor furniture 102 foot 100 system 129 may include an article of outdoor furniture 102 with a space between the substantially vertical wall 124 and internal wall 132 which is configured to receive one of the prong systems 108, 110. In certain examples, the space between the substantially vertical wall 124 and internal wall 132 may have a width which allows the foot 100 to selectively contact portions of the article of outdoor furniture 102. The space between foot 100 and the substantially vertical wall 124 and/or the internal wall 132 may allow the foot 100 to bend, distort or deform, thereby reducing the internal stress on the article of outdoor furniture 102. In particular examples, the width of the space between the substantially vertical wall 124 and internal wall 132 have the same width as the prong system 108, 110, which may create a friction fit.
In certain embodiments, as shown in
With renewed reference to
Advantageously, the foot 100 may allow the article of outdoor furniture 102 to reduce the internal stress placed on the article of outdoor furniture 102, thereby increasing holding strength. For example, the use of a foot 100 under stress tests involving glass surfaces and 200 pound weights demonstrated that articles of outdoor furniture 102 utilizing four feet performed substantially better than articles of outdoor furniture 102 without feet. Further, articles of outdoor furniture 102 without all four feet lost anywhere from 47%-70% of their holding strength. The foot 100 is secured by the protrusions 134, mitigating lateral forces which can damage the foot 100 and the prong system 108, 110. This allows the foot 100 to withstand greater forces and prevent the prong system 108, 110 from becoming decoupled, thereby increasing safety.
It should be appreciated that the article of outdoor furniture 102 may encompass various tables, benches, stools, chairs, containers, storage units, and other suitable articles of outdoor furniture 102 known to those skilled in the art. The foot 100 may be used with any article of outdoor furniture 102 regardless of whether the article of outdoor furniture has legs, or the method used in forming the article of outdoor furniture 102. Likewise, it should also be appreciated that the foot 100 may encompass a variety of different shapes and structures to accommodate different articles of outdoor furniture 102. To that point, the foot 100 may include a base pad 104 that is configured to militate against sliding with respect to a specific ground surface, improving friction and thereby increasing skid resistance. The anchor portion 106 may also be altered to accommodate for increased lateral forces and torsion. Similarly, the complementary ridge 120 and channel 122 configuration may incorporate a variety of shapes and structures. Different configurations of the complementary ridge 120 and channel 122 may be utilized by those with skill in the art. For example, the complementary ridge 120 and the channel 122 could contain additional ridges and channels, or mating grips, advantageously strengthening the connection between the anchor portion 106 and the base pad 104.
The foot 100 may be coupled to an article of outdoor furniture 102 by various methods. As shown in
As shown in
In a particular example, removing the foot 100 from the article of outdoor furniture 102 would result in breaking either or both the foot 100 and the article of outdoor furniture 102. In more particular example, removing a foot 100 that is coupled to the article of outdoor furniture 102 by the methods shown in
Advantageously, the foot 100 for the article of outdoor furniture 102 has enhanced durability, provides a means to adequately retain the foot 100 to the article of outdoor furniture 102, and does not greatly add to the cost of manufacturing the article of outdoor furniture 102.
Example embodiments are provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms, and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail. Equivalent changes, modifications and variations of some embodiments, materials, compositions, and methods can be made within the scope of the present technology, with substantially similar results.
This application claims the benefit of U.S. Utility application Ser. No. 63/252,733 filed on Oct. 6, 2021. The entire disclosure of this application is incorporated herein by reference.
